# Arq8 Design System

## Overview

Arq8 describes itself as: “FullDissolve™ creatine engineered for complete solubility and 10x better absorption — clinically-proven to support mental clarity, physical performance, and long-term cellular health.” The interface is light, built on **White (#FFFFFF)** with **Charcoal (#191919)** text, and **Yellow (#F5FE5E)** as the main accent.

Type is set in **GT Canon** and **Alia-Helvetica**. Headlines run large; body text is 14px. Depth comes from hairline borders and inset highlights rather than drop shadows. Corners are mostly 12px.

Measured from [arq-8.com](https://arq-8.com/) on November 6, 2026 at 1440×900 and 390×844 from 246 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 13 roles.

- **White (#FFFFFF):** Page background, seen 8 times. Token `background`, CSS `--color-white`.
- **Charcoal (#191919):** Primary text and headings, seen 24 times. Token `on-surface`.
- **Near Black (#000000):** Headings and emphasis, seen 10 times. Token `on-surface-strong`, CSS `--color-variant-hover-text`.
- **Near Black (#030302):** Secondary text, seen 3 times. Token `on-surface-variant`, CSS `--color-primary-button-hover-border`.
- **Slate (#5D5D5D):** Muted text and metadata, seen 4 times. Token `on-surface-muted`.
- **Snow (#F5F5F5):** Raised areas one step from the page, seen 4 times. Token `surface-container-low`.
- **Mist (#E2E1E4):** Cards and panels, seen 6 times. Token `surface-container`.
- **White 85% (#FFFFFFD9):** Translucent fill for cards and controls, seen 1 time. Token `overlay`.
- **White 40% (#FFFFFF66):** Borders and dividers, seen 1 time. Token `outline`.
- **Yellow (#F5FE5E):** Brand color in the header. Token `primary`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.
- **Vivid Red (#F02020):** Accent in the logo, seen 1 time. Token `secondary`.
- **Vivid Red (#E0001B):** Accent, seen 8 times. Token `tertiary`.

## Typography

**GT Canon**, **Alia-Helvetica**, **Helvetica** and **Arial** share the interface. Fallback stack: `GT Canon, sans-serif`. Other loaded fonts: Geist, Roobert, Alia-GT-Canon.

- **headline-display:** GT Canon 45px at weight 300, line height 1.1 (28px on mobile). Page title (h1).
- **headline-lg:** Alia-Helvetica 32px at weight 700, line height 1.2, tracking -0.016em. Section headings (h2).
- **headline-md:** Helvetica 26px at weight 400, line height 1.25 (18px on mobile). Sub-section headings.
- **body-md:** Helvetica 14px at weight 400, line height 1.1. Body text.
- **body-lg:** Alia-Helvetica 16px at weight 400, line height 1.2, tracking -0.031em. Lead paragraphs.
- **label-md:** Arial 16px at weight 700. Buttons, navigation and labels.
- **label-sm:** Helvetica 13.5px at weight 600, line height 1.25. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 8% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 3px, sm 7.5px, md 15px, lg 22.5px, xl 45px.
- **Sections:** 90px vertical padding between major sections.
- **Gaps:** 41.26px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1440px.
- **Page margin:** 15px on each side of full-width sections.
- **Breakpoints:** 650px, 700px, 749px, 750px, 768px, 990px, 1024px, 1200px, 1400px, 1919px.

## Elevation & Depth

Depth comes mostly from hairline rings and inset highlights on tonal surfaces (#F5F5F5 → #E2E1E4):

- `rgb(211, 206, 197) 0px 0px 0px 1px inset`

A few raised panels add a soft drop shadow: `rgba(0, 0, 0, 0.15) 0px 3px 15px 0px`.

## Shapes

Most elements use 12px corners. Measured radii, most used first:

- **md (12px):** 72 elements.
- **sm (6px):** 4 elements.
- **full (9999px):** 4 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“SHOP NOW”):** #191919 fill, #FFFFFF text, 14px/400, 6px radius, padding 13.5px 36px 10.5px 36px.
- **button-ghost (“Skip to content”):** transparent fill, #030302 text, 14px/400, padding 16px 24px, shadow `rgb(211, 206, 197) 0px 0px 0px 1px inset`.
- **input-field (“Enter your email”):** #FFFFFF fill, #000000 text, 16px/400, padding 0px 0px 0px 16px, border 1px solid #949596.
- **card:** #FFFFFF fill, #030302C2 text, 14px/400, padding 0px.
- **link:** transparent fill, #FFFFFF text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #F5F5F5, #E2E1E4.
- Do keep text in 4 levels: #191919, #000000, #030302, #5D5D5D.
- Do use #F5FE5E as the brand accent: header, logo and key highlights.
- Do reuse the measured spacing steps (7.5px, 15px, 22.5px).
- Do use 12px corners on most elements; larger surfaces also use 6px.
- Don't use heavy drop shadows; keep depth to hairline rings and tonal surfaces.
- Don't introduce new font families beyond GT Canon, Alia-Helvetica, Helvetica and Arial.
- Don't use #F5FE5E for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.125s, 0.3s, 0.2s, 0.25s. Longer ambient animations run 2s.

- **Easing:** `ease-in-out`, `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
